-LRB- CNN -RRB- -- Rock singer Sammy Hagar , a little older since his Van Halen days but still featuring bountiful blond curls , touted single moms , family and sex Monday night on the premiere of HLN 's `` Dr. Drew . ''

But for Van Halen fans , Hagar 's memories of the band and how he would like to regain a friendship with Eddie Van Halen may have been the biggest draw .

`` The greatest part of my musical career was being in Van Halen , '' said Hagar , who described to Dr. Drew Pinsky the alcoholism in his father and former bandmates .

One of the band members , Hagar said , went into rehab and got clean , but `` Eddie keeps falling down and would be in denial . ''

Hagar , 63 , claims Eddie Van Halen , who he says is doing better these days , is perhaps jealous of his success since leaving the band , a power hard rock mainstay of the 1980s and 1990s .

`` They threw me out of the band , and they have n't done anything since 18 years later , '' said Hagar , author of a bestseller `` Red : My Uncensored Life in Rock . ''

`` He 's got the biggest heart in the world , '' Hagar said of Eddie Van Halen .

In other comments , Hagar :

-- Recalled dreaming as a young man about an alien encounter , with blue beings and beams of light . `` You can call me crazy all you want . Anyone who says we are the only life in this whole vast universe , they are crazy . ''

-- Admitted to many sexual consorts during his days on the road and between marriages . Now , `` I chase my wife around the house . ''

-- Talked about being raised by a single mother in an abusive marriage . `` My mother made me feel love . ''

-- He also spoke about his father who he said died in the back of a police car . `` Because of my father I am very sensitive to it , '' Hagar said of alcoholism .

-- Touted old-fashioned hard work . `` I was willing to work my butt off for anything I could achieve , '' Hagar said . `` I came from nothing . ''

Pinsky , who has been a physician for 30 years , opened the show with an answer to critics who say he ca n't diagnose at a distance .

`` I have studied thousands of cases ... It 's what I do . ''

He said his work includes family issues , sex , addiction and other aspects of the `` human experience . Why we do what we do . ''
